A timely exposé on the dangers of AI as well as assisted suicide and the nature of trust, The Deepest Fake had me glued to the pages from the first gripping chapter until the soul-satisfying finale. You see, not only was it thought-provoking in the extreme, but the root-for-able main characters and riveting, fast-paced plot meant that it worked its magic on me within the first couple of pages. From there, I became so immersed in the near-future setting and character-driven storyline that there wasn’t a chance of me putting this book down. A hypnotic mix of speculative fiction, psychological thriller, and just a bit of family drama, this novel was as haunting as it was thrilling. Bravo, Mr. Kalla, you’ve got yourself a brand-spanking-new fan right here.
With an adrenaline-fueled game of cat-and-mouse at its core, there were multiple other ingredients that battled to be the star feature of this unputdownable tale. With a medical mystery, a possible conspiracy, and some juicy domestic drama, there was no end to the question of what could really be going on. What really got my attention, however, was the depth to this novel. From the two intense character studies of Andrea and Liam to the exploration of the inherent dangers of AI, this book would make a perfect book club selection. Prescient and timely but also deeply poignant, I was blown away by Mr. Kalla’s obvious skill. After all, the multiple plot lines came together with utter precision as the unguessable truth came into view.
All said and done, from the heart-pumping action to the biting commentary on the future of tech, I was won over by this new-to-me author in no time at all. After all, the short, cliffhanger chapters and “WTF?!” twists kept me on the edge of my seat from beginning to end. I’m not exaggerating in the slightest as I actually had to stop myself from skimming in order to find out the whos, whats, and whys even faster. Rife with eerie foreboding and doubt-inducing paranoia, this razor-sharp novel had everything I could want in a thriller: multiple motives, plenty of suspects, and a race against time. So if you’re looking for a definite five star read, be sure to grab a copy ASAP. After all, this one’s sure to top my list of favorite books of the year. Rating of 5+ stars.
P.S. If you’re reading this, dear author, please oh please make this book into a series?! After all, I’d love to follow Andrea around as she does her investigations into scoundrels and cheaters and she starts dating again…

Wow! This was my second Daniel Kalla book and he is now a must read author for me.
Liam Hirsch is the CEO of high tech AI company. He’s about to launch his biggest AI app yet. Unfortunately, someone might be out to sabotage him. Is it someone in his office? His wife? Or an old nemesis? And what’s really going on with his health???
I think sharing more details would ruin the experience. I highly recommend you going in blind! The only details I really knew were that this was about an AI tech company. That was it. This is a wild conspiracy theory thriller that I highly enjoyed! I loved it!

What if you couldn’t trust your own reality?
“In THE DEEPEST FAKE, a tech CEO and AI pioneer has everything to lose—his wife, his company, his life. But as the betrayals mount and his mind begins to unravel, one question remains: Is it all in his head, or is someone rewriting his fate?”
I’m a BIG fan of Daniel’s work and, while all his books grab my attention, this one kept me turning pages into the wee hours of the morning.
I started this one as green as an Irish shamrock - I’ve never tried ChatGPT, heck, I didn’t even know what ‘generative AI’ meant! I finished this book with heightened skepticism and awareness. I’ve definitely been questioning everything in the last few days …
Let me tell you WHY you need to read this one:
- There’s a medical mystery (Kalla’s signature) that will keep you guessing and leave you mindblown. I didn't predict the outcome because I didn’t know the extent or the far-reaching consequences of the technology that someone driven by revenge would resort to using.
- There’s a private investigator hired to uncover the ‘truth’ about a loved one; Kalla crafts a skillful PI who gets at the heart of the indiscretion and walks a fine line of professionalism. Even the ‘gotcha’ moments had me questioning the evidence.
- Great red herrings! Great cast of potential ‘bad guys’.
- Technothriller presented in an easy-to-understand way
- The theme of trust is so prevalent in a rapidly changing world
- Tension created by a rapidly progressing illness and the desire to get everything wrapped up before it’s too late.
- Unpredictable outcomes
If you like unveiling truths, restoring the balance of power, being surprised by genius plotting, enjoy stories that challenge you to ponder ethics, and crave opportunities to think critically about the intersection of technology and humanity, this one’s for you!

✨ Rating: 3.5 ⭐️
🫧 Vibes: black mirror, twisty
🎶 Song: is there someone else? - the weeknd
📚 Would I recommend? sort of.
💬 Final thoughts: interesting thriller but a little too predictable.
In the package:
📦 conspiracies
📦 short chapters
📦 multi-POV
Liam Hirsch is the CEO of an AI company but he's suddenly diagnosed with ALS and also discovers his wife is cheating on him. But when odd events start to occur in his life, he starts to question everything. Is he actually sick or is someone messing with him?
The concept of this book sounded really interesting and it had a lot of potential with black mirror vibes but it didn't land as I hoped it would. I figured out the twist in the end, which was a little too predictable even though the book points fingers at several people.
The creepiest part of this book? How effortlessly AI can twist reality and fool everyone.
Thank you Simon & Schuster Canada for the arc!

You can always count on Daniel Kalla to deliver a page-turning, compelling read!
Set in Washington state, Liam Hirsch has it all - a loving family, he is the CEO of a thriving AI company, and his future is financially secure. However, in a matter of a few weeks he makes discoveries regarding his health, marriage and company that things aren't as wonderful as they seem.
Could all of this be a result of AI?
A haunting and thought-provoking read!

The Deepest Fake by Danielle Kalla. Thanks to @kayepublicity for the gifted Arc ⭐️⭐️⭐️⭐️
Liam is about to launch a new product at his AI company. Things are looking up until he’s diagnosed with a fatal illness. After the diagnosis, strange things keep occurring that make him wonder if there’s more behind his illness.
This one was very suspenseful and hard to put down. I don’t always enjoy stories related to matters within in businesses, but there were no boring parts in this at all. It was focused more on the CEO and what he was experiencing. There is an AI ethical component that’s part of the plot. It makes the reader think about the future and what may entail. I loved the mystery of this one and his partnership with a PI.
“It’s foolish to think we can keep playing God without occasionally flooding the world on the scale of Noah’s ark.”
The Deepest Fake comes out 7/29.

This is the second AI thriller book I've read this year, and I am kinda loving them! Why not deepen my fear of AI more?
The Deepest Fake is a fast paced, who-dunnitesque thriller that has notes of sci-fi (when it comes to the AI jargon). It was pretty good, but I found it to be a bit predictable. Regardless, I still had a great time reading it and was invested in it in the beginning. It slowed a bit for me in the middle.
I have recently found a new love for thrillers that have creepy AI in them and this satisfied that itch. I do wish that there would have had more of it but the bits and pieces that were in there were terrifying enough.
Overall, was a good thriller!

The Deepest Fake
Daniel Kalla
reviewed by Lou Jacobs
readersremains.com | Goodreads
Most people are concerned—and even fearful—about the rapid escalation of AI technology. In The Deepest Fake, Daniel Kalla spins a masterful thriller, shrouded in a “ticking tomb” mystery, while delving into the ethical and moral implications of this advancement.
Public anxiety is heightened by a chilling event in the novel: a “deepfake” video, generated using AI, sways the outcome of an electoral campaign.
Liam Hirsch is the CEO of the tech company TranScend. His team is working toward launching an even more advanced app called Their Story, which uses an algorithm to compile publicly available data into a realistic, “thinking” avatar of any individual. But as the launch nears, Liam faces two personal crises. Not only is his health rapidly deteriorating, but he also suspects his wife is cheating on him. When he consults a neurologist, he receives a dire diagnosis: ALS (Amyotrophic Lateral Sclerosis), a fast-progressing neurodegenerative disease that leads to muscle weakness, atrophy, and ultimately, the loss of the ability to walk, talk, swallow, and breathe. There is no cure.
Liam hires private investigator Angela DeWalt to confirm his suspicions about his wife, Celeste. At the same time, he uncovers evidence that someone on his staff is embezzling company funds.
Angela quickly provides proof of Celeste’s infidelity. With his world collapsing, Liam begins to consider MAID (Medical Assistance in Dying) to spare his children the pain of watching his prolonged decline. (MAID is legal in Canada and several U.S. states. It allows terminally ill, mentally competent adults with a prognosis of six months or less to receive physician-assisted end-of-life medication, which they self-administer.)
But then Liam begins to suspect that someone may have altered his medical records, manipulating his diagnosis. What if he doesn’t have ALS at all? What if he’s being poisoned? Desperate for answers, he turns once again to Angela to help uncover a deep-seated conspiracy.
Daniel Kalla proves himself a masterful storyteller, skillfully weaving multiple plotlines with twists, unexpected turns, and rising suspense. His background as an ER physician adds authenticity to the novel’s medical elements, grounding the high-stakes narrative in real-world plausibility. With compassion and objectivity, Kalla examines the moral and ethical dilemmas surrounding both AI technology and assisted suicide—two of the most controversial topics of our time.
Chapters alternate between the perspectives of Liam and Angela, creating a fast-paced, propulsive read. Shootouts and murder by self-driving car further intensify the novel’s exploration of our growing fears around technology’s dark side.
Thanks to Simon & Schuster for providing an Uncorrected Proof in exchange for an honest review. The Deepest Fake demands attention—and encourages a deeper dive into the impressive oeuvre of Daniel Kalla.

“But it felt real. That’s what I’m trying to tell you, Liam. people could relive their worst regrets, their deepest guilt, and they’ll be doing it with a machine that doesn’t understand boundaries.”
From the moment I picked this up, I couldn’t put it down. Deeply character driven, I was instantly pulled into Liam’s plight, feeling the sense of impending doom as time literally ran out. With the many situations Liam was dealing with, infidelity, terminal illness and possibly a corporate conspiracy within his own company, it’s no wonder I was furiously flipping pages!
Liam’s life is literally imploding so he turns to a private investigator, Andrea, who has her own experiences with broken trust. Told from both of their POVs, they each felt fully fleshed-out and relatable. For that matter, EVERY character felt all too real, adding to the atmosphere of distrust and providing a never ending list of suspects.
Not only was this gripping, emotional and fast paced, it was wholly thought provoking. After all, an app that utilizes AI to allow you to interact with people who have died has all sorts of morally grey and even psychological implications. Not to mention the possibilities of using representations of LIVING people that could lead to never ending deepfakes. What’s the cost of utilizing these advanced technologies, and is it worth it?
Daniel Kalla taps into very real fears regarding the use of AI, as well as tackling tough and divisive topics such as Medical Assistance In Dying (MAiD), and the nature of trust. THE DEEPEST FAKE is an utterly relevant and timely techo-thriller of the highest order. If you’re a fan of high stakes thrillers and enjoy emotional depth as well as exercises in intellectual ‘what ifs’ then this is a MUST READ! This is absolutely one of my top reads of the year.

Did Not Finish
August 30, 2025DNF @30pgs - In a reading slump and can’t bring myself to ever pick this up. The writing is good though.
August 6, 2025
I love it when books can be so close to reality that it becomes scary. That’s what this book does with AI. Great Canadian author and great read.
January 2, 2026
I liked the initial concept of the mystery, but for me there was a bit too much focus on AI and the ending seemed a little rushed or maybe incomplete.

Another hit from one of my fav authors, Daniel Kalla.
I received a gifted copy of this one from Simon and Schuster Canada (thank you, thank you!!!) and I held on to it. I never want to read his books right away because I know I will sit down, read it in an evening and be left waiting for the next one. I was right.
This one follows Liam Hirsch, a CEO of an AI company. Liam finds out he has been diagnosed with a terminal illness, his wife is cheating and he is trying to decide how he wants to live his final days. Then things start to happen and everything becomes a question, namely: is his AI technology being used against him.
It is a quick paced, short chaptered read. I couldn't stop turning these pages. Its packed with ethical questions around AI and end of life decisions. It tucks in Andrea, a private investigator making you question if anything is ever private.
As with many of his books, I find myself thinking about where I stand on these topics and what decision I might make in these circumstances. Its a story I will recommend to others just so I can keep talking about it.
It is only such a talented author who can put together stories like this, bringing you complex situations, show a multitude of sides and make you never stop thinking about it. Also having met him in person, just a incredibly kind human too!

Daniel Kalla has really carved out a niche for himself, using his medical background and gifted storytelling to create medical thrillers that are always timely and entertaining. You would think he would run out of ideas or that the books would start to blend together, but each is incredibly unique.
The Deepest Fake, both engrossing and thought-provoking, explores the consequences of AI and deepfakes and also touches on the complexities of an ALS diagnosis and the debate surrounding Medical Assistance in Dying (MAiD). The pacing was excellent, and I was left guessing until the very end. I was totally wrong about “whodunnit,” and I love when that happens. The characters were realistic and human and really made the book shine. Andrea, the private investigator, is flawed and complex but so likeable. I would love to see her featured in another book!
Thank you so much to Kaye Publicity, Simon & Schuster Canada, and Daniel Kalla for my gifted copy in exchange for an honest review.

Daniel Kalla strikes again! He has become one of my top suspense/mystery/thriller writers without a doubt. And the fact that he's Canadian is just a huge bonus. I have greatly enjoyed each of his books I have read to date, and must go back in time for more.
The premise of this book couldn't be more current - it's all about AI and the potential it raises. Scary . . .
Liam is the main character, who owns a tech company. He believes he has a terminal disease and is in the process of arranging his own death via MaiD. He has a wife, Celeste, and twin teenagers, Cole, and Ava. He has to inform them, but has hesitations. Then he comes across some information which sends him on a search for answers.
Once you know what Liam knows, will you be able to figure it out before he does?
Kalla is a master of suspense & intrigue. His characters are well-developed, and his descriptions are complete. He is very knowledgeable, and the fact that he is first and foremost an ER doctor adds the inclusion of medical issues, along with the usual forensic details. Plot twists abound.
Thank you, Daniel Kalla for another winner!

This was definitely a page turner! There were some concerning considerations about AI being involved in our lives. At the same time some equally concerning considerations about business partners being involved in our lives. I liked the characters development. The suspense remained consistent until the end! The main characters all took a turn at being the prime suspect, with good reason. This was a very thought provoking novel. Frighteningly relevant right now.

Just when you think thrillers can’t get any more relevant… along comes THE DEEPEST FAKE!
I’ve been a longtime fan of Daniel Kalla’s writing—his thrillers are smart, fast-paced, and rooted in the most chillingly plausible “what ifs.” His latest dives headfirst into the world of AI and deepfake technology, and let me tell you… it’s as terrifying as it is timely.
I love how Daniel Kalla never misses a beat when it comes to weaving real-world science into nail-biting suspense, and this one is shaping up to be one of his most thought-provoking yet !
Huge thanks to simonschusterca for the gifted copy

A whodunit that held my interest and flagged important issues / concerns about artificial intelligence.

Another page turning thriller from my favourite Canadian ER doctor. Daniel Kalla has delivered a timely speculative fiction novel exploring the potential dangers and drawbacks of AI.
Liam Hirsh is the successful CEO of his AI company. He's been working day and night developing a new and "improved" version of an AI program. However he soon discovers all is not right with his health, his marriage or his company. Is the AI program behind it all or is someone manipulating the scenarios. As usual, Kalla throws out some red herrings to keep you guessing as to what's really going on. I had my suspicions where he was going with it but it was interesting to read how it all played out in the end.
Another 5* creepy read proving how dangerous AI can be if it finds its way into the wrong hands.
Recommended.

Exploring current and complex topics of AI, the meaning of trust and even MAiD. Lots to consider in this novel.

My mind flip flops between the good that AI can bring to medical advancement or ease of every day life … to the extreme fear that you won’t be able to trust anything or anyone. Which lends into the mental health arena of paranoia and panic.
Do we exchange mental health over AI, can AI bring destruction at the same time as advancement?…. And in the wrong hands does it become a weapon.
Cue the newest @dan book that teeters between medical thriller and contemporary fiction as the plot unravels a devastating diagnosis and company espionage. It uses the authors medical knowledge (fyi he’s an ER doc in his daily life!) as the backbone of story and injects the fears of AI advances to fill the plot.
It’s full of sneaky characters, family secrets, medical side effects and someone trying to take down the guy at the centre of it all: Liam, the CEO of an Artificial Intelligence company. Everyone’s a suspect and he can’t even trust the digital footprint that is laid out in front of him.
As with all of DK books, it’s one you can binge on 1 sitting. But this one stroked my fears of life with AI threatening to take over more and more of our lives… and grasping desperately to life before it all.
